Just a question, is the back area of the Watch series 7 bigger or the same size as the series 6. that is the part with the sensors?
I have not measured but I assume it's the same as that is where the charging puck fits and that is the same size since AW0
 
I mean, that is entirely up to you whether you get an AW7, but, WHY is this a reason? Curious…
Sometimes the blood oxygen level doesn't work. I thought if a bigger area in the sensor, or a smaller on, it might be more focused. The watch runs great, holds the charge, has the current updates. I am going to wait until the sensor has something I can use such as glucose readings, but then again.... it might only read a non evasive attached probe. Not really non evasive, they do have a tiny probe that goes into the skin. Oh well, I can wait, and if I should kick off, well it won't matter. I do know when I do change, it is going to be red. arghhhh

The blood oxygen is pretty poor. I would absolutely not consider it as part of buying criteria, only a "side feature". Hopefully that is improved in the S8.
